国际化和validate="true"，为什么JSP加载就报FreeMarker template error!

[小行星0906]

先加载代码JSP页面，

			<s:form action="loginValidate" validate="true">
				<s:textfield name="username" key="username"/>
				<s:password name="password" key="password"/>
				
				<s:submit key="submit"/>
			</s:form>

validate="true"这个去掉页面就加载正常
但是我还想用校验框架，这个东西太好了，可以同时进行前端和服务端验证。

但是加上后，打开页面下面就黄色FreeMarker template error!

去掉后正常，配置没错，去掉验证后正常.


struts2.3.16 + jdk1.7(在myeclipse8.6里面选择的编译版本1.6) + tomcat-6.0.37

我参照这个例子，全部复制的依然报这个错误，谁给个意见？！！！ http://www.blogjava.net/flying/archive/2008/10/07/232959.html?opt=admin

FreeMarker template error!


Method public java.util.List org.apache.struts2.components.Form.getValidators(java.lang.String) threw an exception when invoked on org.apache.struts2.components.Form@6b633d
The problematic instruction:

 in include "/${parameters.templateDir}/${parameters.expandTheme}/form-close-validate.ftl" [on line 25, column 1 in template/xhtml/form-close.ftl]

http://struts.apache.org/development/2.x/docs/form 好像意思是说只有xhtml和ajax可以用这个validate属性的

谢谢，现在已经不太追究这个问题了，但是多了个了解途径，以前真没好好看过下struts的帮助文档
